Understanding Sound and Singing

Jessi and Sam explore how sound is produced using a balloon and vocal folds analogy. Jessi demonstrates how tightening and loosening the balloon's neck changes pitch, similar to how vocal folds work. They discuss breathing, sound production, and the importance of breath control in singing. Jessi uses a rubber band to illustrate sound amplification, comparing it to the vocal system. The video concludes with an invitation to learn more about the human body and the world.
